Package includes 1 x leak detector Product overview A compact, handheld leak detector designed for HVAC and refrigeration work, propane and halogen gas detection, and general leak troubleshooting. Stepless sensitivity adjustment and fast response make it suitable for onsite inspections and routine maintenance. Key benefits Fast detection and response: warmup in about 6 seconds and instantaneous response to leaks, saving inspection time. Adjustable sensitivity: stepless sensitivity control lets you tune detection level for tight joints or larger leaks. Clear alerts: audible warning and front panel indicator lights increase in speed and flash rate as leak level rises for easy interpretation. Long battery life: low power design and a precision voltage regulator provide up to about 50 hours of use under normal conditions. Durable and portable: lightweight ABS housing with a 20 cm probe for accessing confined or hardtoreach areas. Main features Working temperature: 0 to 52 Celsius. Power supply: 4 x AAA batteries (not included). Warmup time: about 6 seconds. Probe length: 20 cm. Response time: instantaneous. Battery life: about 50 hours under normal use. Mode: unlimited. Reset time: 2 to 10 seconds. Material: ABS plastic. Maximum sensitivity for halogen: 6 gr. Size: 15.00 x 4.50 x 3.50 cm (5.89 x 1.77 x 1.38 in). Color: Yellow. Indicator lights: front panel lights for leak warning and battery voltage indication. Automatic functions: sensitivity can be adjusted at any time and the instrument can automatically adapt to the detection state; poweron reset and automatic followup help ignore background concentration of halogen gas during detection. Low power electronics: precision voltage regulator IC and ultralow power consumption design for stable operation. Practical applications HVAC and refrigeration maintenance: locate refrigerant leaks in systems, valves, and fittings quickly during service and repairs. Propane and gas appliance checks: inspect connections and tanks for propane leaks in kitchens, grills, and portable heating equipment. Field inspections and commissioning: portable design and long battery life make it suitable for building inspections, maintenance rounds, and troubleshooting in the field. What you get One leak detector, ready to use after installing 4 AAA batteries (not included). Compact size and probe length make it easy to carry and operate in tight spaces. Notes Follow normal operating precautions for gas detection equipment. batteries as needed and allow the unit to warm up before use for performance.
